/**
 * This function creates a Smarty object and sets it up for use within our
 * podclass app, setting up some variables.
 *
 * WARNING: If you are using pieforms, set them up BEFORE calling this function.
 *
 * The variables that it sets up are:
 *
 * - WWWROOT: The base url for the Mahara system
 * - USER: The user object
 * - JAVASCRIPT: A list of javascript files to include in the header.  This
 *   list is passed into this function (see below).
 * - HEADERS: An array of any further headers to set.  Each header is just
 *   straight HTML (see below).
 * - PUBLIC: Set true if this page is a public page
 * - MAINNAV: Array defining the main navigation
 *
 * @param $javascript A list of javascript includes.  Each include should be just
 *                    the name of a file, and reside in js/{filename}
 * @param $headers    A list of additional headers.  These are to be specified as
 *                    actual HTML.
 * @param $strings    A list of language strings required by the javascript code.
 * @return Smarty

 * This function creates a Smarty object and sets it up for use within our

 * The variables that it sets up are:
 *
 * - WWWROOT: The base url for the Mahara system
 * - USER: The user object
 * - JAVASCRIPT: A list of javascript files to include in the header.  This
 *   list is passed into this function (see below).
 * - HEADERS: An array of any further headers to set.  Each header is just
 *   straight HTML (see below).
 * - PUBLIC: Set true if this page is a public page
 * - MAINNAV: Array defining the main navigation
 *
 * @param $javascript A list of javascript includes.  Each include should be just
 *                    the name of a file, and reside in js/{filename}
 * @param $headers    A list of additional headers.  These are to be specified as
 *                    actual HTML.
 * @param $strings    A list of language strings required by the javascript code.
